Abstract: A caliper-jaws type release which includes a cam-shaped pin for pivotally holding one of two opposing jaws in the release holder. The cam-shaped pin has a head portion, an eccentric middle portion of smaller diameter than the head portion and a concentric end portion of smaller diameter than the middle portion. The head portion has a recess in its top surface for receiving a lever having a complimentary projection. Inserting the lever into the complimentary recess permits the cam-shaped pin to be rotated. The eccentric portion pivotally engages the jaw. Rotating the cam-shaped pin with the lever causes the jaw to change position relative to the opposing jaw.

Abstract: An improved release for a bow string comprising: a base member, a sear, a latch for releasably holding the sear, and an operating device for moving the latch and freeing the sear to release the bow string. The latch is pivotally connected to the base member and the operating device is slideably carried by the base member, such that relative movement between the operating device and the base member operates the latch. An adjustment device is provided for changing the bias force supplied to the operating device and for changing the distance that the operating device has to move before engaging the latch. The base member can be supported in by the hand in either Concho style or wrist style.
